I am disappointed with the Ace stuff as well. I don't know if it just doesn't work properly in MyCareer, but I don't really see anything different from opposing teams. They all play the pick and roll the same way by doubling me and leaving the roller wide open. Combine that with the CPU making all types of contact layups, I can score 85-90% of the time doing pick and rolls. Makes me feel guilty even using the pick and roll.
I recall reading that a double would sometimes come if a smaller player was guarding a big. Haven't seen that once yet. Last time I've seen this was on last gen. It's very cool seeing Kawhi and Klay start the game off on you, but when I first seen it, I thought it was just smart AI but it seems they are the only players that do such a thing. When I was hearing about all of this, I was thinking it would be a possibility my coach would even put me on the best player sometimes and etc.
Overall, I am disappointed with the ace stuff. Just thought I would see big differences in teams. But I am still enjoying the game. Only thing that's killing the game for me is the defensive rotations, how Mike wont adjust the CPUs ability to make contact layups and midrange shooting and I mean my teammate and opposing CPU. I mean, I don't see how anyone can't see how frequent those are. And last but not least, the amount of unnecessary fouling. I know people say HOF - SIM is supposed to be fake. But for me it feels slightly better than SS. Seems like the CPU actually miss a little more from mid and you can sometimes contest shots without it being a foul. And it's more competitive for me. But fix all that and I'll be good. Because it seems like the midrange success didn't apply to the CPU.
